Heritage Guns' Comment

John Dickson & Son are most famous for their trigger plate actions, both in side/side and over/under configuration, but they also made a wide range of more mainstream guns, both sidelocks and as in the case of no. 6127, very fine boxlocks. No. 6127 demonstrates perfectly the Dickson philosophy of fine quality in everything they manufactured and although not ground-breaking in any way, the choice of specification and finish are above reproach. The wood is of lovely quality, chequering crisp and even and internally the finishing is perfect.
Interestingly although this gun is sleeved, it is not just any old 'sleever'. Alan Crewe from Purdey's chose to sleeve this gun in 1991 and the job is of the very highest standard. Rather than leave the barrels unattributed, he had his name engraved on the barrels which says a lot for the quality of the work.
This gun represents the classic boxlock of its day, but is of the very highest quality, and this combined with excellent barrel measurements, fine wood and engraving and sensitive restoration makes it an exceptional gun for either game or clays.

The stock is finished with a traditional linseed oil based preparation as used on best guns by one of the top English makers. This finish uses no grain fillers to achieve its deep, smooth lustre, only many hours of alternate build and flatting off of the surface.
